9 Claims, (01. 120- 29) V r r A1thou gh itjwill be understood that-m on"This invention relates to copy holders wherein successive lines ofwritten or printed 'ma tterare exhibited to the copyist in step-by-stepman her with reference to a stationary line, guided More particularly,it comprises 'a copy holder, the forwardly extending base and actuatingvention maybe employed in copy holders where-t in either thelcopysupport or the liner; guide is means of which are extensible toaccommodate typewriters or other keyboard machines of di'fferentsizesand dimensions. I

In order to minimize physical strain on the copyist the material tobecdpied is desirably supported on a holder which is positioned rearward1y of the typewriter and in the direct line of vision. Whensopositioned, however; the opera- I tor must either reach around oracross the machine to adjust the holder or'guide to exhibit moved-onerelatively to therother, I have shown-.; by way of illustration the typewherein'jcopy material, is retained-by clamp Ii) Q aisupportew intocontact withthe surfacerofawcam l8, while the reduced upper end ofpushrod l5 engagesa pair of jacks l9 and-129; A plunger2l-whichisconnected tovthe'panel, H extends througlnholes successivelines of text, or an adjusting mechs anism must be provided for remote"actuation so that the operator, without removing the hands far from thekeyboard of the machine, canQma; nipulate the copyholder as required.Such an operating mechanism is disclosed in my co-pend ing application,Serial No. 405,429, filed August writers of different dimensions, andother keyboard machines. It is an object of my present invention toprovide a copy holder, the base and controlling mechanism "of which areextensible to accommodate the same for'use wit-h machines of differentsizes and dimensions.

A further object of the invention H a remotely actuated copyholderwherein a single, horizontally movable, lever at'the front of themachine is actuatedwithinsvelectiveglimits normally to cause the copysupport to" advance stepby-step with respectto a line gauge but inextreme position to release the copyfholder for return to its initialposition. i

Other and further objects will b e" appaiearj from .the followingdescription and drawings in which i l l Figure 1 is aperspective viewoithe improved Figure 2 isa plan View. n

as requiredand bytightening nuts on the bolts 35 it will be secured inadjustment.

The free end of the lever 32 is guided in its;

horizontal movement by the horizontal bars 2'! justable stop 37.conventional means as for example a thumb screw 38, or by a dog andratchet latching means.

The mechanism for operating the push rod 21 to release the copy holderand permit its returnto initial position is operated by a key 39 in theform of a bell crank lever pivoted on an upstanding ear 40 at the endof-one ofthe front bars'21. Connecting rod 41- is secured in clamping'sleeves 42 and dfiby'means such asset screw 44,-these sleeves alsoserving to secure: a second section vl5 of the rod which carries aswinging tri p lever w. A camlip M on. the trip" lever is adapted toengage and raise the push rod 22 but isnormai-l'y heldretracted out ctoperating p sitionbyaspring 48.

In order to accommodate the: copy holder to any particular machine thenuts on bolts 30' and 26' and the set screw-".44 are loosened whereuponthe front end of the assemblage-His extended so that the free end oflever 32 and key 29 wilt be accessible to the operator immediately infront of "the machine,- and the parts are then secured in selectedposition.

In the modification shown'in Figures-3 and 4 the operation of extendingthe base or frame is simplified by eliminating the release key and thecorresponding adjustment of its connecting rod. In this form "of theinvention provision is madeforl normally looking out the lever 32. froman extreme position in which it actuat'es the 'release mechanismpl'nthis case the base 24 has a pivot 49 upon which a bell crank levertll ismountedin position to be locked by contact with the lever- 32 when thelatter is in its extreme position. The other arm of the bell crank.lever 50 actuates a connecting rod whichhas a cam.

for raising the pushrod 21 and releasing the copy holder slide. A bridgestrip 53 serves to" guidethe connecting rod 5i, and spring .54. holds itnormally retracted-.

What I claim is:

In a copy holder having a copy support and anassociated line guide,adjustable one relative to the other in a step-by-step manner, a base towhich said copy holder is secured in vertical position, a sectionallever for effecting such relative adjustment, said lever being. mountedto extend. beneath a machine with which said copy holder is used, andmeans permitting the extension of said sectional lever to project beyondthe forward edge of such machine.

i 2. In a copy holder having a copy support and a line guide, means foradjusting one relative to the other in a step-by-step manner, a base toto the other in a step-byesteplmariner, a base to which said copy holderis secured in vertical position said base including'jside'members eachformed of extensible sectiohs'and a front member secured therebetweenfor adjustment toward and away from said copy support, means forsecuring said extensible side members in position,

, a lever for actuating aid" adjusting means, said lever being formed ofextensible sections, and means for securing the sections thereof inposition wherein thefreee'nd ofsai'd lever projects forwardly beyond thefront edge of such machine.

4. In a copy holder having a copy support and an associated linefguide,adjustable one relative to the other in a ste'p-by-step' manner, a baseto I which said copy'holder is secured in'vertical position and adaptedto extend beneath a machine with. which said copy holder is used, sidememc said" front members to vary the limits of lever In ord'ertoprevent-accidental: release of the I copy holder-slide the normal throwof. the" ad justing lever" 32 is limited by a stepped block 55betweer'rthetront' bars zi ofthe frame or base,

thelower step 56 ofwiii chflies in the horizontal plane in whichthe-lever moves. By raising'the lever, however, at this limit of itsmovement, and clearing the step 56, further movement is perthis extreme"oi'iitsi'movernent the lever 32 rocks '65 mitted to the" extent oftheupper' step 51. In

theflbell. crank and thereby a'ctuates the release mechanism so that'theslide, then returns to its,

normal position.

From the foregoing adapted. for use with a variety of machines of ferentkinds and izes.

itwill'be apparent'that my invention. provides a copy holder ofstandardized construction which by selective adjustment is movement,whereby tocause relative adjustment of the copy support and line guideaccording to difie'rent line spacingsof copy. H
